Y

' further object tion of this character which is so arranged that the heating elements may be readilyA removed, replaced, or repaire-d.

My invention is illustrated .in the accompanying drawings.wherein:

Figure 1'is a front elevation of a manifold with my heater applied thereto;

' Fig. 2 is a section on the line 2 2 of Figure l; Y y

Fig. 3 is `a section on the line 3---3` of Figure 1;

Fig. 4 is a section on the line 4-4 of Figure 3. v Referring to these drawings 10 designates a metallic outer casing which is open at the bottom and is formed to provide a top plater 11, the front plate 12 and the rear plate 13. The end Aplates 14 are cut away as at 15 from the lower end of the rend plate nearly to the upper end thereof and the margins of this cut away portion are folded upon themselves to form guides to receive slides 16.`

rlfhe upper end of the cut away portion 15 is rounded and the upper end of each slide is rounded so as to embrace the manifold A and fit thereon.

i as to retain the heat within the casing.

Mounted within the'casing and held thereto by a plurality of bolts `or screws 17 engaging the front plate, is a` base 18 ,of'i'nsulating material having the end members Mounted 19 also of insulating. material. upon the inner face of this base 18 by means of binding screws are three or more heating coils 20 and mounted upon the end members 19 are a plurality of heating coils 21. These heating coils are connected to each other and tothe battery of the automobile by conduc-V tors as will now be described so that when the switch on the dash board is turned to is to provide a construc- The interior of this outer casing is preferably lined with rasbestos so inner ends to binding screws 24 and at their outer ends to binding screws 25,. vConnected to all of the binding screws 23 is a lead 26 which extends from the battery of the car.

Extending from onel of the binding screws 22 isk aninsulated conductor 27 which extends to one of the binding screws 24. A, conductor 30 which is insulatedk engages one' of the binding screws 25 and passes across the base 19 to yone of the binding screws 23. From one of the binding screws 22 an insulated conductor 33 is connected tothe binding screws 24 at the other'end of the device, and the binding screws 25 at this end Sleeves 35 of insulating material preferablyit over the wires so as tol fully space these, wires from i any chance contact with the metallic casing.

The wire26 runs to a battery (not shown). In` the operation of this device it'will be obvious that when the switch is turned to permit the flow kof current, the current will flow from the'battery through the-several coils of the heater and then back to the bat-- -teiy and that heat willbe applied to the manifold on three sides thereof. The heating umts practically encircle a portion of themanifold which insures the rapid appli-v cation of heat. The interior of the body, being lm ed with asbestos, furtherinsures the effectiveness of the device as a manifold heater. Set screws` 17a` are disposed at the center of the base 18 and engageV with Athe manifold, thus preventing short circuit by centering the heater. 'n

-lvVhile I have illustrated certain details of construction andv arrangement of parts ivhichI have found to be particularly effec- Vtive in Aactual practice, I do not wish to be` llimited thereto as it is obvious that many changes mightbe made therein without departing from the spirit of the invention yas.
